Equipment and method for preparing ultra-thin glass by utilizing glass fiber melting furnace discharge materials

Abstract

Glass fiber melting furnace discharge materials are adopted as raw materials for preparing ultra-thin flexible glass, so that the comprehensive utilization efficiency of the glass fiber melting furnace discharge materials is improved, waste of glass materials is reduced, and ultra-thin glass products with high utilization value can be produced. The regulator is regulated, so that the gaps of glassforming grooves are controllable, regulation can be performed according to heat shrinkage characteristics of the glass, the primary stretching and forming thickness of the glass can be regulated by matching a first leading-down roller and a second stretching roller, the width of the prepared glass is determined by a vertical edge roller, the vertical edge roller can also be used for fixing two sides of the downwards stretched glass, and shrinkage of the glass while downward stretching is reduced. After the stretched glass turns by a drum, the glass is changed from a vertical state to a horizontal state, and convenience is brought to production. The glass surface can be effectively protected by a glass fiber protection layer on the outer side of the drum, and the quality of the ultra-thinglass is improved. The equipment is simple in structure, reasonable in design, reasonable in design, low in modification degree, low in investment operating cost, obvious in production efficiency andbeneficial to popularization and application.

Description

technical field [0001] The invention relates to a device and a method for preparing ultra-thin flexible glass by using discharge material from a glass fiber melting furnace, and belongs to the technical field of ultra-thin glass equipment. Background technique [0002] With the rapid development of flexible display technology and electronic technology, the demand for flexible substrates is becoming more and more urgent. When the thickness is reduced to a certain limit, glass shows better flexibility and is one of the ideal flexible substrate materials. [0003] Flexible glass refers to ultra-thin glass with a thickness of ≤100 μm. Its main components are ordinary soda-lime glass and alkali-free glass. The production methods mainly include float method, overflow down-draw method, slit down-draw method, and secondary down-draw method. Although the float glass has a large amount of drawing and a wide plate, its technology is relatively mature and does not require secondary proc...

AI Technical Summary

Problems solved by technology

Although the float glass has a large amount of drawing and a wide plate, its technology is relatively mature and does not require secondary processing, but the lower surface of the glass is easily stained with tin during the production process, which is difficult to remove, which increases the production process and leads to huge investment; Although the method can produce continuously, the flatness of the glass is good, and there are few defects, but the forming control is difficult and it is difficult to control effectively; Streaks and knots are produced; the flatness of the secondary down-draw glass is good, and it can efficiently and continuously produce thin-plate glass with high precision, but it is difficult to produce large-sized thin-plate glass

[0004] At present, the production line of alkali-free glass fiber is produced by the pool kiln wire drawing method. In order to ensure the stable drawing of the fiber, a certain amount of glass liquid needs to be released through the position of the glass channel every day, generally 2-5 tons per day, and this part of the glass liquid is wasted. , cannot be used as raw material to re-add into the tank kiln, which not only increases the production cost, but also causes great pollution to the environment
